Yeah, $305 million worth. They started buying Tuesday, so balance sheet report just shows the first two days or so of activity. They are just getting started.

I haven't seen any detail on it. I only just now (when I looked prior to my last post) noticed the line item in the report. Apparently they started reporting on it with the April 16 report. It went from $0 -> $0.95B -> $2.71B -> $3.347B -> $3.948B. A drop in the bucket of the overall balance sheet for sure, but it would be interesting to know which zombies the Fed are helping to continue to eat brains.
